68 engine. Correct balancer for engine??? Um... it bolts on... it has only 1 way to bolt on (due to 1 hole being offset, ask me how I know...)... and spins when the engine spins..... yup it's the correct one... :poke:
Honestly though your guess is probably better than mine. I'd assume it's the correct one as it's the one that was already on there when I got the car. There are 2 indentations (look like slices cut in it) that I'm assuming are timing marks on the blancer.
